Description
Technical Field
The utility model relates to the technical field of ceramic rollers, in particular to a ceramic roller structure of a TOPCON sintering furnace.
Background
The conventional TOPCON sintering furnace is mainly divided into a conventional furnace belt type sintering furnace and a ceramic roller way type sintering furnace, and the conventional furnace belt type sintering furnace takes away a large amount of heat due to circulation in and out, so that the energy consumption is 60% higher than that of the ceramic roller way type sintering furnace. At present, a ceramic roller-type sintering furnace is generally adopted for TOPCON battery sintering, but as the size of a silicon wafer is continuously optimized and becomes larger, the silicon wafer becomes thinner, and the roller structure of the ceramic roller-type sintering furnace exists: 1. a blocking piece problem; 2. temperature field stability problems; 3. size compatibility issues, especially rectangular sheets;
in the production and manufacturing process of the crystalline silicon solar cell, the front surface of the silicon wafer needs to be printed with sizing agent to form positive and negative electrodes of the cell. After the paste is printed, drying and sintering are required to be added, so that the organic part of the paste volatilizes, and the metal paste can form metal-semiconductor contact (metal-semiconductor contact) with the silicon wafer; the sintering temperature field and atmosphere field control of the proper sintering temperature and temperature are particularly critical, the conventional sintering furnace is a furnace belt type sintering furnace, the furnace belt circularly rolls to drive the battery piece to move forward, and most of heat can be taken away by the furnace belt circularly, so that the energy consumption is higher.
In order to solve the problems, the ceramic roller type sintering furnace with lower energy consumption is generally adopted in the industry at present, and mainly, a roller type is adopted in a cavity to drive a battery piece to move forwards, and the roller is continuously kept in a high-temperature thermal field atmosphere, so that heat energy loss caused by cold-heat exchange does not occur. However, there are two main structures of the ceramic roller sintering furnace of the current mainstream, one is a roller structure proposed by patent CN 212023768U, and the advantage of the structure is that the rollers below the battery are connected in a penetrating manner, so that the heat storage effect is provided below the battery, the thermal field loss is small, and the temperature of the upper surface and the lower surface of the battery is ensured to be controlled relatively independently. But at the same time, the distance between the battery piece and the lower roller is smaller, which is easy to cause the abnormality of battery piece clamping and betting piece, and once the clamping and betting piece machine is stopped, the machine must be cooled and the debris and sundries are cleaned, so that the productivity is reduced; another roller structure proposed in CN 111392322A has the advantage that the rollers below the battery are cut off, thus ensuring that the chips fall into the chip slots below the machine when the battery is used to hold the chips, thereby not affecting the operation of the machine and improving the utilization rate of the machine. However, the design structure has the problems that the middle roller is disconnected, the thermal field is easy to be lost, the temperature control of the upper surface of the battery piece is seriously influenced, the upper and lower temperature control is not facilitated, and the ceramic rollers on the two sides are not easy to coaxially move, so that the machine is easy to relatively deviate after long-term operation.
Therefore, we propose a ceramic roller structure of a TOPCON sintering furnace.
